An NSX administrator is reviewing syslog and notices that Distributed Firewall Rules hit counts are not being logged. What could cause this issue?

The reason Distributed Firewall Rule logging may not be occurring is that the logging feature for the firewall rules is not enabled. In VMware NSX, each firewall rule can be configured for logging, which allows the administrator to track hits to specific rules and monitor traffic patterns. If logging is not explicitly enabled for certain rules, no hit counts will be recorded even if traffic matches those rules.

This feature is critical for security auditing and troubleshooting, as it provides insights into the effectiveness of firewall configurations. Without enabling logging on the Distributed Firewall rules, an administrator will not have visibility into the traffic being processed by those rules, leading to a lack of recorded hit counts.

Properly configuring the logging settings for firewall rules is essential for monitoring and ensuring the security posture of the virtual network environment. Regular reviews of these settings help maintain visibility into network activity and compliance with security policies.
